Thanks for your very candid reply.. I tried Reaper & what I don't like about Reaper is that when I import a MIDI file into, it has no sound, seems like I have to allocate or put in sounds, & I'm afraid I know nothing about VST' & Vsti, etc. Mixcraft will play as soon as I get a Midi file into it.

I'm running Windows 7, 32 bit.., I've never tried Adobe Audition or Sonar.
Which versions do you have? & do they have Trial periods?
